MOROCCO

1. INTRODUCTION

Aquaculture first started in 1956 in the form of growing-out stations for imported oyster seed, south of Casablanca. This strictly private activity limited to the Atlantic coast, only concerned its direct promoters and was the object of any state intervention.

In 1985, aquaculture sector was limited to four oyster farms. The seed was imported and the were dependent on foreign technology.

Three of the farms are located on the Atlantic coast (Oualidia) and they produce a total of 200 t of oyster (MEDRAP - TD/86/06).

The fourth farm (MAROST) is the only one located on the Mediterranean coast in the lagoon of Nador (about 11 000 ha).

It was first exploited for shellfish culture in 1982 by a group of Breton oyster farmers who were put in charge of installing oyster beds. The initial results were encouraging and therefore inspired a more ambitious project of complementing the oyster with clam, shrimp, sea-bass, sea-bream and grey mullet farming (following the study of TCP/MOR/2308). The Government saw this as a source of local employment (1 000 employments are scheduled) and a creation of new resources.

2. CURRENT STATE OF AQUACULTURE

2.1 Marine aquaculture

Since MAROST seems currently synonomous with Maroccan aquaculture (Review of the Mediterranean Regional Aquaculture Project - GCP/REM/049/ITA) most of this chapter will deal with it. The construction of the station started in November 1985, utilizing an old hydroplane base and all the structures scheduled, in the first programme, are now achieved. At present MAROST has almost full control on the lagoon and 250 people are employed in the project. MAROST activities can be summarized as follows:

  1. Shellfish department

    The hatchery, built in 1986, is in a position to produce 150 million spat of flat oyster (O. edulis) and 50 million spat of clam (Tapes decussatus). Prefattening of oyster is carried out in the lagoon or in open sea.

    The scheduled production of oyster for 1987 is 15–20 t.

    Fattening is carried out in the lagoon.

    Prefattening of clam is carried out by means of special sieves or in “beds” in the lagoon.

    Fattening is carried out in the lagoon. To date (March 1987) 2 ha have been planted.

  2. Shrimp department

    The activity started in 1985 with the realization of a 1 ha pond for P. kerathurus rearing. In 1986, post-larvae of P. japonicus were introduced and results showed a better growth than P. kerathurus (25 gr in 3–4 months).

    30 ha of ponds (1/2 ha each) are presently (March 1987) at disposal for shrimp rearing.

    MAROST schedules a hatchery which will produce 10 million post-larvae/month for 7 months/year. A temporary unit for artificial reproduction has been carried out. MAROST has now about 300 broodstock.

  3. Fish department

    Fry supply (sea bass and sea bream) is now assured by fish collection.

    Prefattening is carried out in raceways and fattening in cages (fixed and floating).

    A fish hatchery with a capacity of 2.5 million fry/year and a fattening unit in intensive and semi-intensive ponds are scheduled.

  4. Research department

    It assures the follow-up of the production and the development of research in different sectors: control of the production, anatomy, hystology, parasitology, bacteriology and virology. The studies currently undertaken concern: gonads development in natural stock of clam, identification of local pathogens, preparation of vaccines.

    I.S.P.M. (Institute Scientifique de Pêche Maritime), counterpart agency nominated in the MEDRAP project document, has a laboratory in MAROST facilities and it is carried on the hydrobiological study of the lagoon and the follow-up of the lagoon in relation with the production activity (PAP/RAC-MEDRAP-TR/87/03).

2.2 Freshwater aquaculture

The Ministry of Agriculture has a fresh-water hatchery at Azrou for restocking purposes. There exists a development project in Oum-er-tbia springs for trout farming aiming at a yearly production level of 300 t, located at 200 km from Marrakech.

3. PROGRAMME

The MAROST programme includes:

3.1 Shellfish

Construction of a depuration station following OMS recommendations. This will enable the society to sell the product in foreign countries.

-   Trials of oyster rearing in open sea

-   Enlargement of the zone of production

-   Verification of the viability of the ‘bed methods’ for clam rearing.

3.2 Shrimp

-   Carrying out the construction of the hatchery

-   Rearing of 500 000 P. japonicus post-larva in 1987

3.3 Fish

-   Improvement of the techniques of fry collection

-   Identification of new areas of exploitation on the Mediterranean and Atlantic coasts

-   Improvements of the fishing techniques in the lagoon by means of new instruments

-   Study of a floating cage adapted to the local environment conditions

-   Eel rearing

-   Introduction of new species

-   Construction of the fish hatchery

-   Construction of a feed manufactory for fish and shrimp (20 t/day capacity)

-   Training activities in connexion with the University programme.

4. PRODUCTION

To date there are no data on the MAROST production. Small quantities of eels have been collected and sold to foreign countries (Italy). General data on Moroccan production show: lagoonal production: 15 kg/ha/year (fish); a total of 200 t of shellfish (MEDRAP - FD/85/11).

5. MARKETING

In terms of fish trade balance Morocco shows a positive figure (see Fig. 1). Morocco is, in fact, the largest exporter along with France and Spain; Their combined share of total exports amounts to about 70%. Data on per caput fish consumption as at 1978 report 5.2 kg/year (ADCP/MR/79/5). On the whole, Morocco is self-sufficient in sea products.

The new production will, therefore, be oriented toward export markets. In particular, fish culture production at Nador, with the exception of grey mullet, is oriented toward the Spanish market or more generally towards western Europe (shrimp).

Both present and planned oyster production is aimed at the Casablanca and Oualidia (restaurant) markets.

6. INSTITUTIONAL CONTEXT

In the last Five-Year National Plan (1981–85) the Moroccan Government established priorities for aquaculture development, favouring investments both from the private and public sector (MEDRAP - FD/5/11). However, marine aquaculture is not governed by a specific administrative body (MEDRAP - TD/86/06). At national level the infrastructure consists of very limited human and material resources provided by I.S.P.M. (Institut Scientifique de Pêche Maritime) which is now transferred to MAROST facilities in Nador. No data on the new five-year national plan are available.
